Difference in Trans Output Shaft Size 1987 and 1988 D50 Sport Power Ram 4x4

[pavichm]

Hi all,
I just picked up a 1987 Dodge D50 Sport Power Ram 4x4. It's in pretty good shape with 110K. Black with gold stripes. The truck runs good but has major transmission issues. Third gear is out along with other problems...locks up at random. The seller threw in a spare transmission/transfer case out of an '88 4x4. I thought it would be an easy swap to get the old girl back on the road.

I proceeded to take out the gearbox and install the spare. Encountered no issues at all until I went to install the rear drive shaft. The yoke is just a little bit smaller than the output shaft in the '88 trans. The front shaft slides in with no problem.

I contacted the seller to see if he had the drive shaft but said it went to the boneyard along with the truck. Any ideas? I don't feel like messing with the internals. Rather like to purchase an '88 drive shaft yoke from someone here on the forum.

Any info would be appreciated.

Thanks!

Mark

If they are the same transmission they should have the exact same size output shaft. Only time they would be diff sizes from what I've seen is from Auto to manual driveshafts. Kind of odd.

swap the transfer cases - they will interchange

Yeah, that's what I'm thinking of doing if I can't get a yoke or find the driveshaft in the boneyard. Can I remove the transfer case with the tranny installed? I hate to pull that thing again! Here is a pic of the yoke that's too small.
